.1: This invention' relates to metallic' skis andmore particularly I to a ski having a toot-supporting filler block of-wood "embraced by a snow-engage One "object of --'the present 'invention 'is to': provide :a. composite wood and -metal ski of the above nature, in which the filler block is held upon the base by: a pair of- Z'-'sh'apedmetal anchor members 'weldedorsold'ered to said base;

shaped "cover members' or metal telescopedwith:- in the-upstanding-sides of'the U"shaped"b'ase.'

A further object is to providea ski of the above nature inwhich provision isxmadeor a metal reinforcing point at? the upturned =forWard part of the base which is secured rigidly in position by welding or soldering;

A further object is'to provide a compositewood and "metalski of the above natureywhich' willibe simple in construction, inexpensive to manufac' ture; easy to assemble; compact; ornament'a'l'in appearance and. very efiicient and 1 durable :in use.

With these wand other objectsin view; there has been illustrated: on the accompanying-"draws ing one-termini which theinvention: may con:- veniently be embodied in practice:-

Fig. 11 is a perspective longitudinal sectional 2" view or the upturned curved forward portionbf the ski;

Referring new to 'the drawing; in which like reference numerals denote corresponding jparts throughout the several views, the numeral -l0indicates the flat base of theski.which-is'=U -shaped in cross section and constructed of corrosion=resistantmetal. The 'base' Iii hasa longitudinal groovel in its bottom surface-'and is provided with'a pair of upturned sides 12 and"! 3 -connected with a pair'of downturned inner wings I4 and i5 located Within said upturned sides l2"and-l3-, as clearly shown-in Figs. 8 and 9.

Provision'is also made-of a foot-supporting fill-- er block Iiiseated in said U-shapedbase l fl and embraced'bysaidwings I4 and l5; 'Ihe'filler block--|6-'-has a raised foot rest-section 11 located slightly to the rear of the mid=p0intof the skl base-10.

The fillerblock lt is adapted to beheld securely upon the base lliby means "of apair of rear and front -Z'-shaped anchor members I IS: IS, the upper flangesof which are adapted to overlieand -engage the flat ends of the block l 6 (as clearly shownin Figs. 2, 3; 4, and 7) The rear portion of thefiiler block 'iiiand the rear anchor member l8 areadapted to beembraced by a Ushaped cover member ZU- haVing a -downturned =rear=edge2l fitted inside an upturned rearedge'22' ofthe base lilof the ski.

The rear 'cover member 20 is providedwith 'depending sides 23; 24 which (as shown iri-Figr8 are adapted to fit tightly within and be secured asby-Welding or soldering to the inner downturned wings it; IS 'Of the metal ski base Ill:

At the -front of the 'ski', provision is made-of 'vve'l'ding or soldering; to "the do'wnturnediwings 14flfibf'thesides'lt' l3 ofth'e'skrba'se I 0; The cover-member 25 is also welded to a. curvedu shapedreiniorcing point 26 of thicker metal than the, sheet material of the metal-base Ill.

The fille'rrbl'ock' l 6 "is adapted" to be'detach ably connected "to a foot harness-:by'means ofja pairof horizontal, headed screws 27; ,ZB'scre'Wed into-:th'e opposite ."sides. of ithe:raise'dfisectibn I l of said fil'l'eriolock '16, the straps of said" harness being indicated in dotted lines by the numerals 29, 30, in Fig. 9.

For the purpose of reinforcing the headed harness attaching screws 21, 28, provision is made of a narrow U-shaped thin metal bracket 3| lying transversely underneath the foot rest I! and having a longitudinal groove 32 interfitted with the groove H in the bottom of the ski base it).

Operation In the manufacture of the composite wood and metal ski of the present invention, the base will preferably be rolled into the shape of a U from a strip of metal by any suitable mechanism, (not shown). The undersurface of the lower flange of the rear Z-shaped anchor member 18 will then be welded to the top surface of the base at the position shown in Fig. 2. The elongated wooden filler block I 6 with the reinforcing bracket 31 attached thereto will then be laid Within the base ill in the position shown in Fig. 2, with its rear end inserted under the upper flange of the anchor member 18. The forward anchor member IE will then be welded or soldered to the base l0 in the position shown. The next step in the assembly of the ski will be to install the telescoping protecting covers 20, 25, as clearly shown in the drawings, which covers may then be welded or soldered to the inner wings of the base I0.

While there has been disclosed inthis specification, one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration on'y, and that the invention is not to be limited to the specific disclosures, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent is:

4. A ski as defined in claim 3, in which the upturned sides of said base are provided with downturned inner wings, and the downturned sections of said cover members are fitted within and secured to said wings.

5. In a ski, an elongated metal base having upturned sides, a filler block anchored in said base and fitted within the sides thereof, said filler block having a raised foot rest, a pair of horizontal harness-attaching headed members projecting from the opposite sides of said raised foot rest above the edges of the upturned sides of said metal base, and a U-shaped metal reinforcing bracket having its side members embracing said headed members and located between said base and said filler block.

6. In a ski, a substantially flat elongated metal base having upturned sides, a top filler block seated in said base between the sides thereof, and a pair of Z-shaped filler block holding anchor members having their bases secured to the base of the ski at the front and rear ends of said filler block.

7. In a ski, an elongated metal base having upturned sides, a filler block seated within said base and fitted within the sides thereof, means to secure said filler block to said base, a pair of inverted metallic cover members having downturned sections to embrace the front and rear portions of said filler block, said downturned sections being telescoped within the upturned sides of said base, and means to secure the sides of said cover members to the upturned sides of said base.

8. In a ski, an elongated metal base having upturned sides, a filler bock seated within said base and fitted within the sides thereof, means to secure said filler block to said base, and a pair of inverted metallic cover members having down turned sections to embrace the front and rear portions of said filler block, said downturned sections being telescoped within the upturned sides of said base, the sides of said cover members being welded to the upturned sides of said base.

9. In a ski, an elongated metal base having upturned sides, a filler block seated within said base and fitted within the sides thereof, means to secure said filler book to said base, a pair of inverted metallic cover members having downturned sections to embrace the front and rear portions of said filler block, said downturned sections being telescoped with respect to the upturned sides of said base, and means to secure the sides of said cover members to the upturned sides of said base.
